【选型】聚洵运算放大器GS8041助力智能睡眠枕传感器,输入失调电压0.4mV,静态电流600nA
智能睡眠枕通过检测鼾声,利用气囊调整睡姿降低鼾声,内部包含振动传感器、MCU、ADC等器件,其中传感器输出信号微弱,不能直接输入ADC进行处理,需要运算放大器调理信号,要求具有功耗低、精度高、尺寸小的特性。
针对智能睡眠枕中传感器输出信号调理的应用,推荐聚洵的单通道轨到轨运算放大器GS8041,采用CMOS工艺设计,工作电压1.4-5.5V,增益带宽积14.5KHz,输入失调电压0.4mV,输入失调电压温漂2.5μV/℃,输入偏置电流1pA,以下是GS8041单通道运放的典型电气性能参数:
1、智能睡眠枕通过振动传感器检测鼾声,其输出的测量信号是微弱模拟信号,需要调理才能进入ADC处理,轨到轨运放GS8041可以提供12.5KHz的增益带宽,工作电压1.4-5.5V,满足振动传感器输出模拟小信号的放大需求。
2、振动传感器输出的模拟信号非常微弱,器件本身引入的失调电压和电源纹波都会影响测量精度,GS8041的输入失调电压只有0.4mV,PSRR电源纹波抑制比达到80dB,可以降低传感器输出信号放大后的非线性误差,提高测量精度。
3、智能睡眠枕采用电池供电,对内部器件功耗要求较高,GS8041的静态电流600nA,可以降低非工作状态下的产品功耗,提高电池使用寿命,同时该器件的ESD等级达到6KV,满足可靠性要求,以下是GS8041典型封装和引脚定义。
